if he is spencers son and spencers asa's son maybe they don't want him(hugh) because who would he be able to have romances with he isn't related to, or at least her kids are related to him. like kelly or blair?

If he has, it was off screen with one of his "model" dates. He hasn't had relations with another character. He liked Marcie - went on a date with her - she went back to Michael. He liked Kelly - so her through the most depressing (one of the most depressing) times of her life - she went back to Kevin (so it seems). Hugh is the "go to" guy. He only got one kiss and that was from Marcie to shut her up! LOL
